title: [Application of joint reconstruction with autogenous coronoid process graft to treat temporomandibular joint ankylosis].
abstract: OBJECTIVE
  To evaluate the clinical effect of joint reconstruction by using autogenous coronoid process graft to treat temporomandibular joint(TMJ) ankylosis.
  
  
  METHODS
  Nine cases of TMJ ankylosis from September 2008 to September 2010 were surgically treated by joint reconstruction with autogenous coronoid process graft, using autogenous articular disc or prosthodontic membrane as interpositional material. Mouth opening, occlusion and cone beam CT(CBCT) were used for evaluation before and after surgery.
  
  
  RESULTS
  Satisfactory mouth opening was achieved in all patients and no one got occlusal changes or reankylosis during follow-up. CBCT showed that coronoid process graft reached bone union with the ramus and turned to be round.
  
  
  CONCLUSIONS
  It is effective to cure TMJ ankylosis through joint reconstruction with autogenous coronoid process graft.
